Opportunity network routing method based on node social relationship

TL;DR: In this article, an opportunity network routing method based on a node social relationship is proposed, where a node is enabled to forward a carried message along nodes having similar identity characteristics with the node, such that the message is quickly forwarded to a target node.

Abstract: The invention relates to an opportunity network routing method based on a node social relationship. According to the method, a node is enabled to forward a carried message along nodes having similar identity characteristics with the node, such that the message is quickly forwarded to a target node. The identity characteristics are corresponding to themes of the message. Whether the message is forwarded is judged by a routing decision value. The routing decision value is determined by a degree of influence of the node and a subjection degree of the node to a certain identity characteristic, and the identity characteristic is corresponding to a theme to which a message carried by a current node belongs. By changing a value of a damping coefficient, a relationship between whether the node forwards by employing an opportunity or forwards according to an attribute of the social relationship can be balanced. According to the method disclosed by the invention, the purposefulness and the accuracy of message forwarding are effectively improved, the message is prevented from being forwarded to an irrelevant node to waste energy consumption, and the blindness and the randomness of the message forwarding further can be alleviated; and the method has a certain guiding significance to spread and forward a personalized message.
